201219838 • 六、發明說明： 【發明所屬之技術領域】 本揭示內容有關立體圖像之觀看者所配戴的快門眼鏡 ，其中左及右側圖像被以時間分隔方式顯示，且尤其有關 由於外側光線、諸如照明光所產生之閃爍被抑制的快門眼 鏡0 【先前技術】 被觀看者於三維中觀看之立體圖像可藉由顯示在該右 及左眼具有視差之圖像所呈現。當作呈現立體圖像之方法 的一範例，觀看者配戴具有特定光學特徵的眼鏡、及以視 差所賦予之影像被呈現給兩眼的方法可被提供。譬如，時 間分隔立體圖像顯示系統包含以時間分隔方式顯示複數不 同圖像的顯示裝置、及圖像觀看者所配戴之快門眼鏡的組 合。 該顯示裝置在螢幕上歷經很短之時期及同時交互地顯 示用於該右眼之圖像及用於該左眼的圖像，與用於該左眼 之圖像及用於該右眼的圖像之時期同步地分開提供該等圖 像至該左眼及該右眼。同時，於右眼部份及左眼部份之每 一者處，藉由觀看者所配戴之快門眼鏡具有藉由液晶透鏡 等所構成之快門機件。於該快門眼鏡中，於用於該左眼的 圖像之顯示期間，該快門眼鏡之左眼部份透射光，且該右 眼部份屏蔽光。亦在用於該右眼的圖像之顯示期間，該快 門眼鏡之右眼部份透射光及該左眼部份屏蔽光（例如參考 -5- 201219838 日本未審査專利申請案公告第09- 1 383 84號、日本未審査 專利申請案第2000-3 6969號、與日本未審査專利申請案 第2 000-45 3 43號）。亦即，立體圖像藉由用該顯示裝置施 行用於該右眼之圖像及用於該左眼之圖像的時間分隔顯示 而被呈現給觀看者，且經由該快門機件與該顯示裝置之顯 示切換同步地造成該快門眼鏡施行影像選擇。 被使用於該立體圖像顯示之顯示裝置不被限制於特定 之方法。譬如’除了傳統之CRT(陰極射線管）顯示器以外 ，電漿顯示面板（PDP)、液晶顯示器（LCD)、及電激發光 (EL)面板可被使用。當然，作爲該液晶顯示器，TFT(薄膜 電晶體）被設置用於每一像素的主動矩陣型液晶顯示器係 常見的。藉由將用於每一掃描線之圖像信號由螢幕的上部 朝向其下部寫入來驅動每一像素'及在每一像素阻斷或透 射來自背光之照明光，該TFT液晶顯示器施行顯示。 藉由在該等快門眼鏡之透鏡的前面及後方附接偏振板 ’其係可能阻斷所有光線。.如圖1 8所說明，偏振板通常 被附接至液晶顯示器之最外邊表面。在另一方面，其透射 軸係與該液晶顯示器側面上之偏振板的透射軸對齊之偏振 板被附接快門眼鏡之每一液晶透鏡的前面（該液晶顯示器 側面上之表面）。然後，既然液晶透鏡之透射光的偏振方 向旋轉90度，具有僅只旋轉90度之透射軸的偏振板係附 接至該液晶透鏡的觀看者側面上之表面》 然而，如果該快門眼鏡被造成阻斷所有光線，在此有 —問題’其中非反向器型螢光燈（與一些LED燈）及該液晶 201219838 透鏡互相干擾，以致強烈之閃爍被產生。於該偏振板 置於該液晶透鏡的前面及後方之快門眼鏡的案例中， 等快門被關閉時，如圖1 9 A所說明，該快門眼鏡阻斷 光線。在另一方面，如果該快門被打開，如圖1 9B所 ，既然僅只來自該螢光燈之入射光的偏振方向與立體 對齊之分量貫穿，閃爍被產生。 於圖20A中，由該螢光燈進入該快門眼鏡的光之 被顯示。於該偏振板被設置於該液晶透鏡的前面及後 案例中，入射在該快門眼鏡上之光僅只在該液晶透鏡 開之時期中貫穿，如在圖19A及19B所說明。於圖 中，貫穿該快門眼鏡及接著被該觀看者之眼睛所接收 之亮度被顯示，其中該偏振板被設置於該液晶透鏡的 及後方。既然被該眼睛所接收之亮度每一次該快門被 時即改變，其能被發現產生閃爍。 【發明內容】 其想要的是提供優異之快門眼鏡，其中由於外側 '諸如照明光所產生之閃爍可被抑制。 根據本揭示內容之具體實施例，提供有快門眼鏡 含：液晶透鏡；第一偏振板，被附接至該等液晶透鏡 一者的背面；眼鏡框，其支撐該等液晶透鏡；及第二 板’其係可分離地附接至該等液晶透鏡之每一者的前· 於根據本揭示內容之具體實施例的快門眼鏡之組 ’該第二偏振板可藉著被插入該眼鏡框的邊緣及該液 被設 當該 所有 說明 圖像 亮度 方之 被打 20B 的光 前面 打開 光線 ，包 之每 偏振 哲。 構中 晶透 201219838 鏡間之間隙而附接。 於根據本揭示內容之具體實施例的快門眼鏡之組構中 ，在該第二偏振板中，用於插入該眼鏡框的邊緣及該液晶 透鏡間之間隙的插入翼片可被形成在至少一位置。 於根據本揭示內容之具體實施例的快門眼鏡之組構中 ，該第二偏振板可在至少一位置具有一凹部。 於根據本揭示內容之具體實施例的快門眼鏡之組構中 ，該眼鏡框可具有分別圍繞該右眼及該左眼用之液晶透鏡 的邊緣。該快門眼鏡可另包含鼻樑架，該鼻樑架連接用於 該右眼及該左眼之第二偏振板，且用於該右眼及該左眼之 第二偏振板可藉由在該鼻樑架夾住該等邊緣而附接。 於根據本揭示內容之具體實施例的快門眼鏡之組構中 ，該第二偏振板可在其背面具有低黏性黏著劑，且係藉由 該低黏性黏著劑之黏著力可分離地附接至該液晶透鏡的前 面。 於根據本揭示內容之具體實施例的快門眼鏡之組構中 ，該第二偏振板可在其表面具有可分離之挑取翼片。 根據本揭示內容之具體實施例，既然藉由將該第二偏 振板可分離地附接至該液晶透鏡之前面，該快門眼鏡被造 成僅只阻斷來自該液晶顯示器之已偏振光，且其係可能抑 制由於外側光線、諸如照明光所產生之閃爍。 在另一方面’如果該第二偏振板係不可分離地附接至 該液晶透鏡的前面，於觀看者傾斜該面等之案例中，其係 不可能完全地阻斷來自該液晶顯示器之已偏振光，以致雙 -8- 201219838 影像被輕易地觀察到。於對比下，根據本揭示內容之具體 實施例，藉由根據閃爍或串擾之任一問題是否可被容忍來 使觀看者將該偏振板附接至該快門眼鏡之液晶透鏡的前面 ，其係可能抑制該閃爍或該串擾。亦即，其係可能按照觀 看環境自由地回應該閃爍及該串擾之問題。 本揭示內容之其他目的、特色、及優點將由基於本揭 示內容之具體實施例的更詳細敘述、或所附圖面變得明顯 ，該詳細敘述將稍後被敘述。 【實施方式】 在下文，本揭示內容之具體實施例將參考該等圖面詳 細地敘述。 於快門眼鏡阻斷所有光線之案例中，有一問題，其中 來自螢光燈等之外側光線及該眼鏡彼此干擾，藉此強烈之 閃爍被產生（如上述）。當作該等措施之一，該快門眼鏡之 液晶透鏡的前面之偏振板的移除能被給與。 於圖1 A中，說明當快門係在快門眼鏡1 〇 1中被關閉 時之狀態，其中偏振板1 03係僅只設置在液晶透鏡之背面 上。既然來自液晶顯示器1 04之立體圖像的光線係藉由該 最外邊表面上之偏振板所偏振，該立體圖像之光可僅只藉 由附接至液晶透鏡102之背面（該觀看者上之表面）的偏振 板103所阻斷。在另一方面，既然來自螢光燈1〇5等的外 側光線僅只不被一片偏振板1 0 3所阻斷，其係不可能於該 快門眼鏡1 〇 1中阻斷該光，且該光抵達觀看者之眼睛。於 -9- 201219838 圖1 B中，亦說明當該快門係在該快門眼鏡！ 〇 i中被打開 時之狀態’其中該偏振板1 03係僅只設置在該液晶透鏡 102之背面上》來自該液晶顯示器1〇4的立體圖像之光及 來自該螢光燈1 05等的外側光線兩者貫穿該快門眼鏡1 〇 1 。然而，既然該立體圖像之光被偏振，反之來自該螢光燈 1 05的外側光線不被偏振，該閃爍消失。 然而’如果該偏振板103僅只被附接至該液晶透鏡 1 02之背面，有一問題，其中當配戴該快門眼鏡i i之觀 看者施行諸如傾斜其臉之作用時，雙影像被反射在其眼睛 中。如果該觀看者傾斜其臉，既然該快門眼鏡101之液晶 透鏡102及該偏振板103兩者被傾斜，該偏振軸係由該液 晶顯示器1 04之立體圖像的偏振軸偏離，以致其變得不可 能在該快門被關閉的時期中完全阻斷該立體圖像之光。 於圖1 C中，說明當該快門係在一狀態中關閉時的狀 態，在此具有僅只設置在該液晶透鏡的背面上之偏振板 103的快門眼鏡101被傾斜。既然該偏振板1〇3之偏振軸 係由該液晶顯示器104的最外邊表面上之偏振板的偏振軸 傾斜，縱使該快門被關閉，其係不是可能完全地阻斷來自 該液晶顯示器104之立體圖像的光，以致該光抵達該觀看 者之眼睛。來自該螢光燈1 05等之外側光線亦抵達該觀看 者之眼睛。於圖1 D中，亦說明當該快門係在一狀態中打 開時的狀態，在此具有僅只設置在該液晶透鏡1 02的背面 上之偏振板1 03的快門眼鏡1 0 1被傾斜。甚至當該快門被 打開時，既然該偏振板1 03之偏振軸係由該液晶顯示器 -10- 201219838 1 〇4的最外邊表面上之偏振板的偏振軸傾斜，來自該液晶 顯示器104之立體圖像的光未阻斷地抵達該觀看者之眼睛 。來自該螢光燈1 05等之外側光線亦抵達該觀看者之眼睛 。據此，既然用於該右眼之圖像及用於該左眼的圖像兩者 被反射在該觀看者之右眼及左眼中，串擾被產生，以致雙 影像被反射在該觀看者之眼睛中。 閃爍是否藉由外側光線所產生亦視照明房間之內部的 螢光燈是否爲反向器型而定。該快門眼鏡之偏振軸是否亦 傾斜亦視觀看者觀察立體圖像之方法而定。亦即，閃爍或 串擾是否係在觀看立體圖像之時產生不須僅只視該快門眼 鏡之性能而定。本發明家考慮觀看者可親自地決定閃爍或 串擾之問題是否可被容忍。 因此，本發明家提出將用於觀看立體圖像的快門眼鏡 之液晶透鏡的前面之偏振板製成爲可分離的。如果觀看者 根據閃爍或串擾之問題是否可被容忍而將該偏振板附接至 快門眼鏡之液晶透鏡的前面係可接收的。 於圖2中，與本揭示內容之具體實施例有關的快門眼 鏡之外觀組構被說明。眼鏡框之所說明組構係一般之組構 。亦即，眼鏡框200包含圍繞該右及左透鏡（於此案例中 ，該等液晶透鏡）之邊緣、連接該右及左邊緣之鼻樑架、 在該右及左邊緣之眼睛的外部角落側面經過鉸鏈樞轉地接 合至個別之側面邊緣的右及左眼鏡腳、及在該個別眼鏡腳 之端部末梢被配戴在該等耳朵上之眼鏡腳套。在該邊緣上 支撐該眼鏡腳的鉸鏈部份係亦藉由鏡架所遮蓋。該右及左 -11 - 201219838 邊緣亦在眼睛之內角落側面具有鼻托，且被製成爲由兩側 面夾住該鼻子，藉此固定該眼鏡。該眼鏡框200之基本組 構本身爲常識。 雖然其在圖2中被省略，該偏振板103係附接至分別 藉由該右及左邊緣所支撐之液晶透鏡102的背面（該觀看 者側面之表面上）。 在另一方面，當作將該偏振板可分離地附接至右及左 液晶透鏡102之前面的方法譬如，插入型（參考圖3)、夾 住型（參考圖4)、及黏附型（參考圖5)能被給與。在下文， 每一附接方法將被敘述。 該插入型係藉由將該偏振板附接件的一端部插入該液 晶透鏡及該邊緣間之間隙來附接偏振板附接件之方法。於 圖6及7中，插入型偏振板附接件之組構範例被分別地說 明。該實際尺寸係按照該邊緣之形狀或尺寸任意地決定。 該偏振板當其已被附接至該邊緣之吸收軸的方向被設定至 大約與該液晶顯示器的最外邊表面上之偏振板的吸收軸對 應。 圖6所說明之偏振板附接件6 0 0爲規則之尺寸，且圖 7所說明之偏振板附接件700爲小尺寸者。於任一型式中 ，在該偏振板附接件之眼睛的內部角落側面與眼睛的外部 角落側面之至少一者上，插入翼片601、602及701被形 成在端部。亦於任一型式中，凹部603及702被形成在眼 睛之外部角落側面。 於圖8中，說明偏振板附接件8 01如何被插入該快門 -12- 201219838 眼鏡。液晶透鏡8 0 2經過海綿墊8 0 3被支撐在該眼鏡框之 邊緣8 04上。如果該海綿墊8 03被壓扁，大約0.1毫米至 0. 1 5毫米的範圍中之間隙係形成於該液晶透鏡8 02的表面 及該邊緣8 04之間。該偏振板附接件8 0 1能藉由將插入翼 片805插入該間隙被附接至該快門眼鏡。 於圖9中，說明將插入型式偏振板附接件附接至該快 門眼鏡的狀態。然而，在此中被使用之偏振板附接件係設 定至爲規則之尺寸，在眼睛的內部角落側面與眼睛的外部 角落側面上之兩端部具有該插入翼片，如圖6所說明。 首先，該偏振板附接件之眼睛的內部角落側面上之插 入翼片被插入該眼睛的內部角落上方之邊緣的間隙。隨後 ，在該偏振板附接件之眼睛的外部角落側面，該插入翼片 係在該眼睛的外部角落上方插入該邊緣之間隙。然後，藉 由將該偏振板附接件之下側面推向該液晶透鏡，該偏振板 附接件被裝至該邊緣之內部圓周，並與該液晶透鏡之前面 造成緊密接觸。 亦於圖1 〇中，說明由該快門眼鏡分離以如圖9所示 之方式附接的偏振板附接件之狀態。如該圖面中所說明， 其係可能將指甲放在眼睛的外部角落側面所形成之凹部中 ，且由該邊緣分離該偏振板附接件。 該夾住型爲藉由在眼睛的內部角落側面上之部份使用 該鼻樑架之彈力將該等邊緣夾在該快門眼鏡側面上，附接 該偏振板附接件之方法，其中該右及左偏振板被由彈簧材 料所製成之鼻樑架所支撐》 -13- 201219838 於圖1 1及1 2中，分別說明夾住型偏振板附接件的組 構範例。圖Π所說明之偏振板附接件1 1 〇〇爲規則之尺寸 ，且圖1 2所說明之偏振板附接件1 200爲小尺寸者。該實 際尺寸係按照該邊緣之形狀或尺寸任意地決定。該偏振板 當其已被附接至該邊緣之吸收軸的方向被設定至大約與該 液晶顯示器的最外邊表面上之偏振板的吸收軸對應。此外 ，相對於夾住型偏振板附接件1 1〇〇及1 200之附接方法及 分離方法說明被省略。 該黏附型爲藉由施加至該偏振板之背面側（將與該液 晶透鏡造成接觸的側面上之表面）的低黏性之黏著劑的黏 著力將偏振板固定至該液晶透鏡之方法。 於圖1 3及1 4中，分別說明黏附型偏振板附接件之組 構範例。圖1 3所說明之偏振板附接件1 3 00爲規則之尺寸 ，且圖14所說明之偏振板附接件1400爲小尺寸者》該實 際尺寸係按照該邊緣之形狀或尺寸任意地決定。 爲了防止使用者接觸一表面，藉此用該手弄髒該表面 ，當將該插入型或該黏附型偏振板附接件附接至該快門眼 鏡時、及當將其自該快門眼鏡分離時，其較佳的是在偏振 板1 5 0 1之大約中心處提供挑取翼片1 5 02，如圖1 5所說明 。該挑取翼片1502係譬如藉由二折疊式膠帶所構成。在 附接及分離之時，使用者緊握該挑取翼片1 5 02，且接著操 縱該偏振板附接件1501»然而，在附接之後，該使用者由 該偏振板1501之表面剝除該挑取翼片1 5 02，且接著使用 該快門眼鏡。 -14- 201219838 於圖16中，將插入型或該黏附型偏振板附接件附接 至該快門眼鏡之狀態被說明。 首先，使用者緊握該挑取翼片、舉起該偏振板、且接 著在眼睛之內部角落上方將該偏振板插入該邊緣。隨後， 於該使用者仍然緊握該挑取翼片之狀態中，如果該使用者 在眼睛之外部角落上方將該偏振板插入該邊緣，則該使用 者降低該挑取翼片。然後，藉由推動偏振板之大約中心， 並藉由使用該崩塌之挑取翼片以便防止該指尖接觸該偏振 板之表面，該偏振板附接件係裝至該邊緣之內部圓周，且 與該液晶透鏡之前面造成緊密接觸。在該偏振板附接件被 附接至該液晶透鏡之後，該使用者由該偏振板之表面剝除 該挑取翼片，且接著使用該快門眼鏡。 亦於圖1 7中，說明由以圖1 6所說明之方式附接的快 門眼鏡分離偏振板附接件之狀態。 首先，使用者將由二折疊式膠帶所製成之挑取翼片黏 著至已附接至該液晶透鏡的偏振板附接件之大約中心。然 後，該使用者緊握及拉動該挑取翼片，同時小心使該指尖 不會接觸該偏振板之表面。既然該偏振板附接件係僅只藉 由該低黏性的黏著劑黏著至該液晶透鏡之表面，該偏振板 附接件能自該液晶透鏡藉由該拉力被分離。甚至在該分離 工作終止之後，考慮該偏振板附接件之下一附接，該挑取 翼片可保持黏在其上。 雖然於此說明書中，該插入型、該夾住型、及該黏附 型偏振板附接件之每一者已參考該圖面被敘述，本揭示內 -15- 201219838 容之要旨不被限制於所說明之偏振板附接件的特定形狀或 尺寸。 本揭示內容包括有關在2010年6月4日於日本專利 局中提出的日本優先權專利申請案第JP 2010-129422號中 所揭示之主題，其整個內容係以引用的方式倂入本文中。 熟練於該技藝者應了解各種修改、組合、次組合、及 變更可視設計需求及其他因素而定發生，只要它們係在所 附申請專利或其同等項之範圍內。 【圖式簡單說明】 圖1A係一圖解，說明當快門係在快門眼鏡中關閉時 的狀態，其中偏振板僅只被設置在液晶透鏡之背面。 圖1 B係一圖解，說明當該快門在該快門眼鏡中被打 開時的狀態，其中該偏振板僅只被設置在該液晶透鏡之背 面。 圖1C係一圖解，說明當該快門被關閉時的狀態，且 在具有僅只設置在該液晶透鏡的背面上之偏振板的快門眼 鏡被傾斜之狀態。 圖1 D係一圖解，說明當該快門被打開時的狀態，且 在具有僅只設置在該液晶透鏡的背面上之偏振板的快門眼 鏡被傾斜之狀態。 圖2係一圖解，說明與本揭示內容之具體實施例有關 的快門眼鏡之外觀組構。 圖3係一圖解，說明使用該插入方法被附接至該快門 -16- 201219838 眼鏡之右.及左液晶透鏡的前面之偏振板。 圖4係一圖解，說明使用該夾住方法被附接至該快門 眼鏡之右及左液晶透鏡的前面之偏振板》 圖5係一圖解，說明使用該黏附方法被附接至該快門 眼鏡之右及左液晶透鏡的前面之偏振板。 圖6係一圖解，說明插入型偏振板附接件之組構範例 〇 圖7係一圖解，說明插入型偏振板附接件之組構範例 〇 圖8係一圖解，用於說明如何將該偏振板附接件插入 該快門眼鏡》 圖9係一圖解，說明將該插入型偏振板附接件附接至 該快門眼鏡之狀態。 圖10係一圖解，說明由該快門眼鏡分離該插入型偏 振板附接件之狀態。 圖1 1係一圖解，說明夾住型偏振板附接件之組構範 例。 圖1 2係一圖解，說明該夾住型偏振板附接件之組構 範例。 圖1 3係一圖解，說明黏附型偏振板附接件之組構範 例。 圖1 4係一圖解，說明該黏附型偏振板附接件之組構 範例。 圖1 5係一圖解，說明設有挑取翼片之黏附型偏振板 -17- 201219838 附接件。 圖16係一圖解，說明將該插入型或該黏附型偏振板 附接件附接至該快門眼鏡之狀態。 圖17係一圖解，說明由該快門眼鏡分離該插入型或 該黏附型偏振板附接件之狀態》 圖1 8係一圖解，說明一狀態，在此來自藉由液晶顯 示器所顯示之立體圖像的光線經過該快門眼鏡之透鏡抵達 觀看者之眼睛。 圖19A係一圖解，用於說明一現象，其中閃爍係由於 螢光燈之光進入該快門眼鏡而在立體圖像中產生，並使該 偏振板設置於該液晶透鏡的前面及後方（在關閉快門之時） 〇 圖1 9B係一圖解，用於說明一現象，其中閃爍係由於 螢光燈之光進入該快門眼鏡而在立體圖像中產生，並使該 偏振板設置於該液晶透鏡的前面及後方（在打開該快門之 時）。 圖20A係一圖解，說明由該螢光燈進入該快門眼鏡的 光之亮度。 圖2 0B係一圖解，說明貫穿該快門眼鏡及接著被觀看 者之眼睛所接收的光之亮度，並使該偏振板設置於該液晶 透鏡的前面及後方。 【主要元件符號說明】 1 0 1 :快門眼鏡 -18- 201219838 102 :液晶透鏡 1 0 3 :偏振板 104 :液晶顯示器 105 :螢光燈 2 0 0 :眼鏡框 600 :偏振板附接件 601 :插入翼片 602 :插入翼片 603 :凹部 700 :偏振板附接件 701 :插入翼片 702 :凹部 8 0 1 :偏振板附接件 802 :液晶透鏡 8 0 3 :海綿墊 8 0 4 :邊緣 1 1 〇 〇 :偏振板附接件 1 200 :偏振板附接件 1 3 00 :偏振板附接件 1 4 0 0 :偏振板附接件 1 5 0 1 :偏振板 1 5 0 2 :挑取翼片201219838 • VI. Description of the Invention: [Technical Field] The present disclosure relates to shutter glasses worn by a viewer of a stereoscopic image, wherein the left and right images are displayed in a time-separated manner, and in particular Shutter glasses 0 such as flicker that is suppressed by illumination light [Prior Art] A stereoscopic image viewed by a viewer in three dimensions can be presented by displaying an image having parallax in the right and left eyes. As an example of a method of presenting a stereoscopic image, a method in which a viewer wears glasses having specific optical characteristics, and an image given by parallax is presented to both eyes can be provided. For example, the time-separated stereoscopic image display system includes a display device that displays a plurality of different images in a time-separated manner, and a combination of shutter glasses that the image viewer wears. The display device displays the image for the right eye and the image for the left eye and the image for the left eye and the image for the left eye interactively on the screen for a short period of time and simultaneously The images are simultaneously provided separately to the left eye and the right eye. Meanwhile, at each of the right eye portion and the left eye portion, the shutter glasses worn by the viewer have a shutter mechanism constituted by a liquid crystal lens or the like. In the shutter glasses, during the display of the image for the left eye, the left eye portion of the shutter glasses transmits light, and the right eye portion shields light. Also, during the display of the image for the right eye, the right-eye portion of the shutter glasses transmits light and the left-eye portion shields light (for example, refer to -5-201219838 Japanese Unexamined Patent Application Publication No. 09-1 383 No. 84, Japanese Unexamined Patent Application No. 2000-3 6969, and Japanese Unexamined Patent Application No. 2000-45 3 43). That is, the stereoscopic image is presented to the viewer by performing a time-separated display for the image of the right eye and the image for the left eye with the display device, and via the shutter member and the display The display switching of the device synchronously causes the shutter glasses to perform image selection. The display device used for the stereoscopic image display is not limited to a specific method. For example, in addition to conventional CRT (Cathode Ray Tube) displays, plasma display panels (PDPs), liquid crystal displays (LCDs), and electroluminescent (EL) panels can be used. Of course, as the liquid crystal display, a TFT (Thin Film Transistor) is provided for the active matrix type liquid crystal display of each pixel. The TFT liquid crystal display is displayed by driving an image signal for each scan line from the upper portion of the screen toward the lower portion thereof to drive each pixel' and to block or transmit illumination light from the backlight at each pixel. By attaching a polarizing plate to the front and rear of the lenses of the shutter glasses, it is possible to block all light. As illustrated in Fig. 18, the polarizing plate is usually attached to the outermost surface of the liquid crystal display. On the other hand, a polarizing plate whose transmission axis is aligned with the transmission axis of the polarizing plate on the side of the liquid crystal display is attached to the front surface of each liquid crystal lens of the shutter glasses (the surface on the side of the liquid crystal display). Then, since the polarization direction of the transmitted light of the liquid crystal lens is rotated by 90 degrees, a polarizing plate having a transmission axis rotated only by 90 degrees is attached to the surface on the viewer side of the liquid crystal lens. However, if the shutter glasses are caused to be blocked Breaking all the light, there is a problem - where the non-inverter type fluorescent lamp (with some LED lights) and the liquid crystal 201219838 lens interfere with each other, so that strong flicker is generated. In the case of the shutter glasses in which the polarizing plate is placed in front of and behind the liquid crystal lens, when the shutter is closed, as shown in Fig. 19A, the shutter glasses block light. On the other hand, if the shutter is opened, as shown in Fig. 19B, since only the polarization direction of the incident light from the fluorescent lamp and the component of the stereo alignment are penetrated, the flicker is generated. In Fig. 20A, the light entering the shutter glasses by the fluorescent lamp is displayed. In the case where the polarizing plate is disposed in front of and behind the liquid crystal lens, the light incident on the shutter glass penetrates only during the period in which the liquid crystal lens is opened, as illustrated in Figs. 19A and 19B. In the figure, the brightness is displayed through the shutter glasses and then received by the viewer's eyes, wherein the polarizing plates are disposed behind and behind the liquid crystal lens. Since the brightness received by the eye changes each time the shutter is changed, it can be found to produce flicker. SUMMARY OF THE INVENTION It is desirable to provide excellent shutter glasses in which flicker due to the outer side such as illumination light can be suppressed. According to a specific embodiment of the present disclosure, a shutter glass is provided comprising: a liquid crystal lens; a first polarizing plate attached to a back surface of the liquid crystal lens; a spectacle frame supporting the liquid crystal lens; and a second plate 'A set of shutter glasses that are detachably attached to each of the liquid crystal lenses, according to a specific embodiment of the present disclosure'. The second polarizing plate can be inserted into the edge of the spectacle frame And the liquid is set to open the light in front of all the light indicating that the brightness of the image is hit 20B, and each polarization of the package. In the structure of the crystal through the 201219838 mirror gap and attached. In a configuration of shutter glasses according to a specific embodiment of the present disclosure, in the second polarizing plate, an insertion fin for inserting a gap between the edge of the eyeglass frame and the liquid crystal lens may be formed in at least one position. In a configuration of shutter glasses in accordance with a particular embodiment of the present disclosure, the second polarizing plate can have a recess in at least one location. In a configuration of shutter glasses in accordance with a specific embodiment of the present disclosure, the eyeglass frame may have edges that surround the right eye and the liquid crystal lens for the left eye, respectively. The shutter glasses may further include a bridge frame connecting the second polarizing plate for the right eye and the left eye, and the second polarizing plate for the right eye and the left eye may be used in the nose bridge Attached by clamping the edges. In the composition of the shutter glasses according to the specific embodiment of the present disclosure, the second polarizing plate may have a low-viscosity adhesive on the back surface thereof, and is detachably attached by the adhesive force of the low-viscosity adhesive. Connected to the front of the liquid crystal lens. In a configuration of shutter glasses in accordance with a particular embodiment of the present disclosure, the second polarizing plate can have detachable pick tabs on its surface. According to a specific embodiment of the present disclosure, since the second polarizing plate is detachably attached to the front surface of the liquid crystal lens, the shutter glass is caused to block only the polarized light from the liquid crystal display, and the system is It is possible to suppress flicker due to outside light, such as illumination light. On the other hand, if the second polarizing plate is inseparably attached to the front surface of the liquid crystal lens, it is impossible to completely block the polarized light from the liquid crystal display in the case where the viewer tilts the surface or the like. Light, so that the double-8-201219838 image was easily observed. In contrast, in accordance with a particular embodiment of the present disclosure, it is possible for a viewer to attach the polarizing plate to the front of the liquid crystal lens of the shutter glasses by whether any of the problems of flickering or crosstalk can be tolerated. This flicker or the crosstalk is suppressed. That is, it is possible to freely respond to the problem of flicker and crosstalk in accordance with the viewing environment. Other objects, features, and advantages of the present invention will become apparent from the Detailed Description of the Detailed Description. [Embodiment] Hereinafter, specific embodiments of the present disclosure will be described in detail with reference to the drawings. In the case where the shutter glasses block all the light, there is a problem in which the light from the outside of the fluorescent lamp and the like interfere with each other, whereby strong flicker is generated (as described above). As one of the measures, the removal of the polarizing plate on the front side of the liquid crystal lens of the shutter glasses can be given. In Fig. 1A, the state when the shutter is closed in the shutter glasses 1 〇 1 is explained, in which the polarizing plate 103 is disposed only on the back surface of the liquid crystal lens. Since the light from the stereoscopic image of the liquid crystal display 104 is polarized by the polarizing plate on the outermost surface, the light of the stereoscopic image can be attached only to the back surface of the liquid crystal lens 102 (the viewer) The surface of the polarizing plate 103 is blocked. On the other hand, since the outside light from the fluorescent lamp 1〇5 or the like is only blocked by one polarizing plate 103, it is impossible to block the light in the shutter glasses 1〇1, and the light Arrive in the eyes of the viewer. In -9-201219838 Figure 1 B, also shows that when the shutter is attached to the shutter glasses! The state in which 〇i is opened, in which the polarizing plate 103 is disposed only on the back surface of the liquid crystal lens 102, the light of the stereoscopic image from the liquid crystal display 1〇4, and the light from the fluorescent lamp 105 and the like Both outer rays pass through the shutter glasses 1 〇1. However, since the light of the stereoscopic image is polarized, and the outer light from the fluorescent lamp 105 is not polarized, the flicker disappears. However, if the polarizing plate 103 is only attached to the back surface of the liquid crystal lens 102, there is a problem in that when the viewer wearing the shutter glasses ii performs the action such as tilting the face, the double image is reflected in the eyes thereof. in. If the viewer tilts the face, since both the liquid crystal lens 102 and the polarizing plate 103 of the shutter glasses 101 are tilted, the polarization axis is deviated from the polarization axis of the stereoscopic image of the liquid crystal display 104, so that it becomes It is impossible to completely block the light of the stereoscopic image in the period in which the shutter is closed. In Fig. 1C, the state when the shutter is closed in a state is explained, and the shutter glasses 101 having the polarizing plate 103 provided only on the back surface of the liquid crystal lens are tilted. Since the polarization axis of the polarizing plate 1〇3 is inclined by the polarization axis of the polarizing plate on the outermost surface of the liquid crystal display 104, even if the shutter is closed, it is impossible to completely block the stereoscopic image from the liquid crystal display 104. The light of the image is such that the light reaches the viewer's eyes. Light from the outside of the fluorescent lamp 105 and the like also reaches the viewer's eyes. In Fig. 1D, the state in which the shutter is opened in a state is also explained, and the shutter glasses 110 having only the polarizing plate 103 disposed only on the back surface of the liquid crystal lens 102 are inclined. Even when the shutter is opened, since the polarization axis of the polarizing plate 103 is inclined by the polarization axis of the polarizing plate on the outermost surface of the liquid crystal display -10- 201219838 1 , 4, a perspective view from the liquid crystal display 104 is obtained. The light of the image reaches the viewer's eyes unblocked. Light from the outside of the fluorescent lamp 105 and the like also reaches the viewer's eyes. According to this, since both the image for the right eye and the image for the left eye are reflected in the right eye and the left eye of the viewer, crosstalk is generated, so that the double image is reflected at the viewer. In the eyes. Whether the flicker is generated by the outside light depends on whether the fluorescent lamp inside the lighting room is an inverter type. Whether the polarization axis of the shutter glasses is also inclined depends on the method by which the viewer observes the stereoscopic image. That is, whether flicker or crosstalk occurs when viewing a stereoscopic image does not need to be solely dependent on the performance of the shutter eyeglass. The inventors considered whether the viewer can personally decide whether the problem of flicker or crosstalk can be tolerated. Therefore, the inventors propose to make the polarizing plate of the front surface of the liquid crystal lens of the shutter glasses for viewing a stereoscopic image separable. Attaching the polarizing plate to the front of the liquid crystal lens of the shutter glasses is acceptable if the viewer is tolerated according to the problem of flicker or crosstalk. In Fig. 2, the appearance configuration of a shutter eye lens relating to a specific embodiment of the present disclosure is illustrated. The composition of the frame of the eyeglass frame is generally a structure. That is, the eyeglass frame 200 includes an edge surrounding the right and left lenses (in this case, the liquid crystal lenses), a bridge that connects the right and left edges, and an outer corner of the eyes at the right and left edges. The hinges are pivotally joined to the right and left temples of the individual side edges, and the temple sleeves on which the end ends of the individual temples are worn. The hinge portion that supports the temple on the edge is also covered by the frame. The right and left -11 - 201219838 The edge also has a nose pad on the side of the corner of the eye and is made to hold the nose by the sides, thereby fixing the eyeglass. The basic structure of the spectacle frame 200 is itself common sense. Although it is omitted in Fig. 2, the polarizing plate 103 is attached to the back surface of the liquid crystal lens 102 supported by the right and left edges (on the surface of the viewer side). On the other hand, as a method of detachably attaching the polarizing plate to the front faces of the right and left liquid crystal lenses 102, for example, an insert type (refer to FIG. 3), a pinch type (refer to FIG. 4), and an adhesive type (refer to FIG. 4) Refer to Figure 5) to be given. In the following, each attachment method will be described. The insert type is a method of attaching a polarizing plate attachment member by inserting one end portion of the polarizing plate attachment member into the liquid crystal lens and a gap between the edges. In Figs. 6 and 7, the configuration examples of the insert type polarizing plate attachment members are separately described. The actual size is arbitrarily determined according to the shape or size of the edge. The direction of the polarizing plate when it has been attached to the absorption axis of the edge is set to approximately correspond to the absorption axis of the polarizing plate on the outermost surface of the liquid crystal display. The polarizing plate attachment member 60 illustrated in Fig. 6 is of a regular size, and the polarizing plate attachment member 700 illustrated in Fig. 7 is of a small size. In either version, at least one of the inner corner side of the eye of the polarizing plate attachment member and the outer corner side of the eye, the insertion flaps 601, 602, and 701 are formed at the ends. Also in either version, the recesses 603 and 702 are formed on the side of the outer corner of the eye. In Fig. 8, it is explained how the polarizing plate attachment 819 is inserted into the shutter -12-201219838 glasses. The liquid crystal lens 802 is supported on the edge 804 of the spectacle frame via a sponge pad 803. If the sponge pad 803 is flattened, a gap in the range of about 0.1 mm to 0.15 mm is formed between the surface of the liquid crystal lens 822 and the edge 804. The polarizing plate attachment member 80 1 can be attached to the shutter glasses by inserting the insertion flap 805 into the gap. In Fig. 9, a state in which an insertion type polarizing plate attachment member is attached to the shutter glasses is explained. However, the polarizing plate attachment member used herein is set to a regular size having the insertion fin at both end portions of the inner corner side of the eye and the outer corner side of the eye, as illustrated in Fig. 6. First, the insertion tab on the inner corner side of the eye of the polarizing plate attachment member is inserted into the gap at the edge above the inner corner of the eye. Subsequently, on the side of the outer corner of the eye of the polarizing plate attachment member, the insertion flap is inserted into the gap of the edge above the outer corner of the eye. Then, by pushing the lower side of the polarizing plate attachment member toward the liquid crystal lens, the polarizing plate attachment member is attached to the inner circumference of the edge and brought into close contact with the front surface of the liquid crystal lens. Also in Fig. 1, a state in which the polarizing plate attachment member attached in the manner shown in Fig. 9 is separated by the shutter glasses will be described. As illustrated in this figure, it is possible to place the nail in a recess formed by the side of the outer corner of the eye, and the polarizer attachment is separated by the edge. The clamping type is a method of attaching the edge to the side of the shutter glasses by using the elastic force of the bridge on the side of the inner corner of the eye to attach the polarizing plate attachment, wherein the right and The left polarizing plate is supported by a bridge made of a spring material. -13- 201219838 In Figs. 11 and 12, an example of the configuration of the sandwich type polarizing plate attachment is explained, respectively. The polarizing plate attachment member 1 1 〇〇 illustrated in the drawings is a regular size, and the polarizing plate attachment member 1 200 illustrated in Fig. 12 is a small size. The actual size is arbitrarily determined according to the shape or size of the edge. The direction of the polarizing plate when it has been attached to the absorption axis of the edge is set to approximately correspond to the absorption axis of the polarizing plate on the outermost surface of the liquid crystal display. Further, the attachment method and the separation method with respect to the sandwich type polarizing plate attachment members 1 1 and 1 200 are omitted. The adhesive type is a method of fixing a polarizing plate to the liquid crystal lens by an adhesive force applied to a back side of the polarizing plate (a surface on a side surface to be brought into contact with the liquid crystal lens) with a low viscosity. In Figs. 13 and 14, respectively, an example of the structure of the adhesive type polarizing plate attachment member will be described. The polarizing plate attachment member 1 300 illustrated in Fig. 13 is a regular size, and the polarizing plate attachment member 1400 illustrated in Fig. 14 is a small size. The actual size is arbitrarily determined according to the shape or size of the edge. . In order to prevent the user from contacting a surface, thereby soiling the surface with the hand, when attaching the insert or the adhesive type polarizing plate attachment to the shutter glasses, and when separating it from the shutter glasses Preferably, the picking tab 1 52 is provided at approximately the center of the polarizing plate 1 501, as illustrated in FIG. The picking flap 1502 is constructed, for example, by a two-folded tape. At the time of attachment and detachment, the user grips the picking tab 152 and then manipulates the polarizing plate attachment 1501. However, after attachment, the user is peeled off from the surface of the polarizing plate 1501 In addition to the picking flap 1 52, the shutter glasses are then used. -14-201219838 In Fig. 16, a state in which an insert type or the adhesion type polarizing plate attachment is attached to the shutter glasses is explained. First, the user grips the pick tab, lifts the polarizer, and then inserts the polarizer into the edge over the inner corner of the eye. Subsequently, in a state where the user is still gripping the picking flap, if the user inserts the polarizing plate into the edge above the outer corner of the eye, the user lowers the picking flap. Then, by pushing the approximate center of the polarizing plate and by using the collapsing picking tab to prevent the fingertip from contacting the surface of the polarizing plate, the polarizing plate attachment member is attached to the inner circumference of the edge, and In close contact with the front face of the liquid crystal lens. After the polarizing plate attachment is attached to the liquid crystal lens, the user peels off the picking tab from the surface of the polarizing plate, and then uses the shutter glasses. Also in Fig. 17, a state in which the polarizing plate attachment member is separated by the shutter glasses attached in the manner illustrated in Fig. 16 is explained. First, the user adheres the pick tab made of the two folded tape to the approximate center of the polarizer attachment attached to the liquid crystal lens. The user then grips and pulls the pick tab while being careful that the fingertip does not contact the surface of the polarizer. Since the polarizing plate attachment member is adhered only to the surface of the liquid crystal lens by the low-viscosity adhesive, the polarizing plate attachment member can be separated from the liquid crystal lens by the pulling force. Even after the separation is terminated, considering the attachment below the polarizer attachment, the pick tab can remain adhered thereto. Although in this specification, each of the insert type, the pinch type, and the adhesive type polarizing plate attachment member has been described with reference to the drawing, the gist of the present disclosure is not limited to -15-201219838.
